It is increasingly observable that in different industries competitors jointly acquire and share customer data. We propose a modified Hotelling model with two-dimensional consumer heterogeneity to analyze the incentives for such agreements and their welfare implications. In our model the incentives of firms for data acquisition and sharing depend on the willingness of consumers to switch brands. Firms ...
It is increasingly observable that competitors in different industries share customer data, which can be used for targeted pricing. We propose a modified Hotelling model with two-dimensional consumer heterogeneity to analyze the incentives for such sharing and its ensuing welfare effects. We show that these incentives depend on the type of customer data and on consumer heterogeneity in the strength ...
The paper investigates the link between bank concentration and a country's buyout market. We perform a macro level analysis for 15 European countries during 1997-2007. We estimate the elasticity of the country i's buyout market to country i's concentration in the banking sector. Our major finding suggests that the more concentrated the banking sector is, the better it is for the size of the buyout ...
In this note, we extend the Goyal and Joshi’s model of collaboration networks in oligopoly to multi-market situations. We examine the incentive of firms to form links and the architectures of the resulting equilibrium networks in this setting. We then present some results on efficient networks.
The economic gap between eastern and western Germany is still sizeable, even 25 years after the fall of the Berlin Wall. In terms of GDP per inhabitant and productivity, eastern Germany has attained nearly three-quarters of western German levels, respectively. Since some years, the catch-up process is advancing very slowly indeed. The main reason for low productivity is the lack of highly skilled jobs. ...
Der wirtschaftliche Rückstand Ostdeutschlands gegenüber Westdeutschland ist 25 Jahre nach dem Fall der Mauer immer noch groß. Beim Bruttoinlandsprodukt je Einwohner werden 71 Prozent und bei der Produktivität etwa drei Viertel des westdeutschen Niveaus erreicht. Der Aufholprozess kommt nur noch sehr langsam voran. Der entscheidende Grund für die geringe Produktivität ist der Mangel an hochqualifizierten ...
